      Doc: dt: arch_timer: discourage clock-frequency use · 4155fc07
      Mark Rutland 提交于
      The ARM Generic Timer (AKA the architected timer, arm_arch_timer)
      features a CPU register (CNTFRQ) which firmware is intended to
      initialize, and non-secure software can read to determine the frequency
      of the timer. On CPUs with secure state, this register cannot be written
      from non-secure states.
      
      The firmware of early SoCs featuring the timer did not correctly
      initialize CNTFRQ correctly on all CPUs, requiring the frequency to be
      described in DT as a workaround. This workaround is not complete however
      as it is exposed to all software in a privileged non-secure mode
      (including guests running under a hypervisor). The firmware and DTs for
      recent SoCs have followed the example set by these early SoCs.
      
      This patch updates the arch timer binding documentation to make it
      clearer that the use of the clock-frequency property is a poor
      work-around. The MMIO generic timer binding is similarly updated, though
      this is less of a concern as there is generally no need to expose the
      MMIO timers to guest OSs.

      Pull power management and ACPI fixes from Rafael Wysocki:
       "These are fixes for recent regressions (PCI/ACPI resources and at91
        RTC locking), a stable-candidate powercap RAPL driver fix and two ARM
        cpuidle fixes (one stable-candidate too).
      
        Specifics:
      
         - Revert a recent PCI commit related to IRQ resources management that
           introduced a regression for drivers attempting to bind to devices
           whose previous drivers did not balance pci_enable_device() and
           pci_disable_device() as expected (Rafael J Wysocki).
      
         - Fix a deadlock in at91_rtc_interrupt() introduced by a typo in a
           recent commit related to wakeup interrupt handling (Dan Carpenter).
      
         - Allow the power capping RAPL (Running-Average Power Limit) driver
           to use different energy units for domains within one CPU package
           which is necessary to handle Intel Haswell EP processors correctly
           (Jacob Pan).
      
         - Improve the cpuidle mvebu driver's handling of Armada XP SoCs by
           updating the target residency and exit latency numbers for those
           chips (Sebastien Rannou).
      
         - Prevent the cpuidle mvebu driver from calling cpu_pm_enter() twice
           in a row before cpu_pm_exit() is called on the same CPU which
           breaks the core's assumptions regarding the usage of those
           functions (Gregory Clement)"
